Abstract
A method for matching an image-form textual string in an image to a regular expression is disclosed. The method includes constructing a representation of the regular expression and generating a candidate string of characters from the image-form textual string. The method further includes ascertaining whether there exists a match between the image-form textual string and the regular expression, the match is deemed achieved if a probability value associated with the match is above a predetermined matching threshold.
Claims21
A computer-implemented method for matching an image-form textual string in an image to a regular expression, comprising:
- constructing a representation of said regular expression;
- generating a candidate string of characters from said image-form textual string;
- and
- ascertaining whether there exists a match between said image-form textual string and said regular expression. said match is deemed achieved if a probabilitv value associated with said match is above a predetermined matching threshold.
An article of manufacture comprising a program storage medium having computer readable codes embodied therein, said computer readable codes being configured for matching an image-form textual string in an image to a regular expression, comprising:
- computer readable code for constructing a representation of said regular expression;
- computer readable code for generating a candidate string of characters from said image-form textual string;
- computer readable code for ascertaining whether there exists a match between said image-form textual string and said regular expression said match is deemed achieved if a probability value associated with said match is above a predetermined matching threshold.
